I've entrusted several people I know with one key of several that can be combined to authorize a transaction from a multisignature bitcoin wallet, and I've also given the location of some of my cold wallets and/or their private keys to my family members as well. I'm not one to leave all my eggs in one basket, so even if one of these wallets fails somehow, there's still at least some of my crypto out there somewhere. Most people in my family aren't too tech-savvy either, but I've also left some basic instructions on how to actually use private keys at the location where they're stored, so that should (hopefully) be enough.
